Answer:

The answer to your question is 6.0 moles of O₂

Step-by-step explanation:

Data

2KClO₃ ⇒ 2KCl + 3O₂

moles of O₂ = ?

moles of KCl = 4

Process

To find the number of moles of O₂, use proportions and cross multiplication.

Use the coefficients of the balanced equation.

2 moles of KCl ----------------- 3 moles of O₂

4 moles of KCl ----------------- x

x = (4 x 3) / 2

-Simplification

x = 12/2

-Result

x = 6 moles of O₂

-Conclusion

When 4,0 moles of KCl are produced, 6.0 moles of O₂ will be produced.
